An example of a downwards wind.

Linedef type 543, Downwards Wind, is a type of linedef special which creates a downdraft inside every tagged sector. If players come into contact with the wind, they will be pushed downwards.


The speed of the wind is determined by the length of the control linedef.

If Flag [9] / Solid Midtexture / Effect 4 is checked, the wind will switch to sliding mode, in which players will be forced into their pain sprites and cannot accelerate or decelerate. If Flag [6] / Not Climbable is checked, the pushing effect is made exclusive – once an Object has been pushed by this effect, it cannot be pushed by any other pushing or carrying effect in the same tic. This is useful if the effect is applied to multiple adjacent sectors, since it would normally be applied twice when an Object crosses the border between two sectors with the effect.
